This research provides a comprehensive spatiotemporal atlas of the human ovary to identify the specific molecular and cellular drivers of aging across three life stages. By utilizing single-cell RNA sequencing and spatial transcriptomics, the authors mapped eight distinct cell types and discovered that DNA damage and heightened inflammatory signaling are central to the decline of oocytes and granulosa cells. A key highlight of the study is the identification of FOXP1 as a vital regulatory protein that decreases with age, leading to increased cellular senescence. The findings suggest that…
